The VWR Professional precision balances are ideal for wide range of laboratory weighing tasks, they have been designed for multi-user environments (each user profile has password protection). These interactive balances which feature an internal database to store data and drying methods, help improve efficiency and productivity. All professional models have a 5” touch screen with icon driven menu, qwerty touch keypad and a stainless steel top pan. Models are GLP set up, storing balance, project and user identification data, as well as date and time. GLP information can be also printed out with results, a statistics printout is available even without a statistical printer.
- Selectable filter levels and user can select the measuring unit that the balance will use to display the weight
- Electromagnetic force restoration or high resolution load cells for accurate weighing
- RS232 and USB data interface allows import/export of data
- Optional integrated ioniser at the rear of the balance
- Live colour indication for check weighing
- Easy to operate and have multiple languages: English, German, French, Italian, Spanish and Portuguese, different users can set different use preferences, each user account is password protected
Functions include suspended weighing, piece counting, percentage weighing, check weighing, density determination, totalisation and statistics function, formulation, textile (thread measuring), maximum load (peak hold) function, animal weighing , internal database to store parameters, settings and recipes.
The user can choose three options for models with internal calibration (denoted by "i" at end of the model name): Balance will calibrate using the internal weight by pressing CAL button. Balance will automatically recalibrate when ambient temperature changes and/or after a certain time has passed (Incal+). The user can choose to calibrate the balance with an external weight.
Models with pipette check function allow you to easily check the tolerances of pipettes in the laboratory following ISO 8655 directive procedures, or lets you define a standard operating procedure. These models have repeatability of 0,001g and a stabilisation time of ≤2 seconds.
